I want to buy a civic then turbo charge it, should i spend the extra money to buy one with VTEC or just stick to the cheaper non-VTEC? Will there be much performance difference between the 2? ie VTEC with Turbo VS non-VTEC with Turbo

 

turbo + vtec is always good...why not have both?

might concern about reliable issue that's it.

 

welcome to H-T now its time to SEARCH...its fun, easy and reliable

LS Turbo
GSR/Si/Type R Turbo

A lot of tech stuff you need to look into in order to make a decision thats good for you.

LS/Vtec Turbo

 

My personal preference are B18B, B20, and H23 are good for force inducting. Turbo'ing vtec engines will have some unreliable issues especially if your on a budget. If you already have a vtec engine just stay N/A, but it's your engine and your personal preference, my $0.02. GL.

 

barefootbonzai how much more would it end up costing you to go lsvtec and such i would honestly turbo the ls you'll get around if not hte same gains save the money for building the block.

No it won't. You slap a turbo kit on a VTEC engine just like any other engine. What's he going to do? Wear out his electronically controlled VTEC?

 

lol..

yea we all know how pesky vtec can get at 10+ psi....

 

sohc vtech turbo the way to go cheap and tons of fun when you beat dohc's

 

Wouldn't want your Turbo to foul out your VTEC bearings.

the b20 sleeves are poop. i think compression is the issue here. lower compression gives you the ability to run more boost, and/or run the same boost with less chance of detonation. most vtec motors are over 10:1 compression, which doesnt leave much area for safety when tuning and should detonation occur, chances are it will be more destructive quicker in a higher compression motor. as someone mentioned earlier, the sohc vtec has a 9.2 and 9.6:1 compression(z6 and y8 respectively), which will let you get vtec and have a relatively larger room for error due to the lower compression. possibly the best thing to do for high hp is use a b series vtec and lower the compression via headgasket and/or lower comp. pistons. this gives you the vtec and excellent flow of a b series head, and the ablility to run more boost/be safer with lower boost. this is definately something that you will have to spend hours upon hours reading about and deciding for yourself, what i said here is just stuff to get you thinking about some aspects of your question

 

a thicker head gasket is great for boost let my friend run 13 pounds of boost with his stock sohc vtec

 

Too broad of a question to begin with, plus if you have turbo specific questions try the Forced Induction forum.
